PROBLEM TO BE SOLVED: To provide a high efficiency stator which can reduce iron loss, by relaxing stress impairment of magnetic characteristics resulting from a compressive stress generated, when the stator is shrinkage fitted to the enclosed container of a compressor, and to provide an enclosed compressor and a rotating machine. SOLUTION: In the stator 2 having a tubular laminated stator core 3 secured to the enclosed container 1 of an enclosed compressor by shrinkage fitting, the stator core 3 has a plurality of slots 5 arranged in the circumferential direction; magnetic pole tees 4 formed between adjoining slots 5 and around which a coil 6 is wound; a plurality of regions 12 divided in the circumferential direction by the radial center line of the magnetic pole tees 4; contact regions 13, i.e. a predetermined number of regions from among the plurality of regions 12, arranged at a fixed interval in the circumferential direction and contacting the inner circumferential surface of the enclosed container 1; and noncontact regions 14 formed between the contact regions 13.
